H.pylori testing is a common test for any GI work-up on acid reflux, indigestion, etc... The problem is it can be highly inaccurate, if they use the blood test. The most accurate way is through endoscopic biopsy (which is very expensive and not necessary for most of us), but they can also test for h. pylori through a stool sample and a urea breath test. I've had all of them except for the stool sample. I had a raging h.pylori infection several years ago and had to go through triple therapy (the antibiotics) twice to get rid of it. Everytime I have an upper EGD, they usually test for h. pylori, even though I don't think I'm any more at risk for re-infection than the general population. I still have stomach problems, which tells me they had nothing to do with the h. pylori infection. If you didn't know, h. pylori is strongly associated with ulcers, and in rare circumstance, gastric cancers. Evidently, I still have ulcer like conditions (erosive gastritis) despite having eradicated my h. pylori infection years ago. I've read some things that indicate that once h. pylori start wreaking havoc on your GI tract, the damage can continue even after successful eradication. Don't know how credible that it, but if I find out (I'll ask my GI doctor), I'll let you guys know.
I guess the bottom line is if you need to be tested for h. pylori, don't settle for the blood test. All the blood test tells you is that you've had the infection in the past; you will stay positive for years after the infection is gone. I would probably have a positive blood test. You really need to have one of the other tests done. If you're having an endoscopy for another reason, insist on an h. pylori biopsy--this is the best method.
